Step-by-step explanation:
A key to understanding the structure and function of nucleic acids is the principle of complementary base pairing. In double-stranded DNA, adenine and thymine always pair (A-T), and cytosine and guanine always pair (C-G). On the other hand, uracil (U) is one of the four nucleotide bases in RNA, with the other three being adenine (A), cytosine (C), and guanine (G). In RNA, uracil pairs with adenine (U-A). In a DNA molecule, the nucleotide thymine (T) is used in place of uracil.
You can determine the sequence of a complementary strand if you are given the sequence of the template strand.
With this information, we can conclude that the correct answer is:
Answer:
The DNA sequence ATGCATGC will pair with the following RNA strand:
a) UACGUACG
